    No Gains

    You won't see any gains because you would be swapping out for the same part. Both ls1 and ls2 GTO's have the ls6 intake.

    They are not the same intake. The LS2 intake will make the same power as the early LS1 intakes untill higher rpm where the 90mm TB gives it an edge.
    The LS6 intake makes more torque and HP through the entire rev range vs the LS2 intake even though it has a smaller TB.

    Depends on what mod level you are at. Heads and Cam cars would benifit from a bigger TB and even an LSX intake. But a bolt on car probably not, you would gain power but not enough to make it worth the expense IMO

    Stock LS6 intake outflows the stock LS2 intake. A ported LS2 intake will outflow a stock LS6 intake.

    Keep what you have. You'd have to change a lot over to make the LS2 work. If you really want to change intakes, get a FAST.
